SN74HC251N Overview
In order to save board space, digital switch is located in the 16-DIP (0.300, 7.62mm).As a result, it is packaged in a way that is referred to as Tube.Digital switch ic adheres to a mounting method of Through Hole.In the multiplexers, the analog IC is indicated by Multiplexer.As long as the operating temperature is -40°C~85°C, turn signal switch will not be influenced by external factors.When digital controlled switch operates at 2V~6V, designers have superior flexibility.Multiplexers from the 74HC series can be used in a wide range of applications.There is a design for terminating 16 as part of its basic configuration.The base part number is 74HC251, which is also useful when looking up signal switch's related components.The multiplexer's system is supplied with a voltage of 5V.In this turn signal switch, there are 16 component pins.As a type of supply, Single is employed.Currently, it is configured with a 16 pin configuration.It is positioned in the direction of Through Hole.In the HC/UH family, the logic switch is included.Signal multiplexer provides 8 bits.Keeping Vsup at 2V will prevent some unwanted failures.In order to avoid unnecessary failures, the maximum supply voltage (Vsup) should be kept at 6V.It is provided that 2/6V has a power supply in order to function normally.As a result, the turn signal switch consists of 1 outputs.When a supply voltage of 5V is used, reliable performance of the multiplexers can be achieved.This multiplexer provides 8 inputs.It is necessary for the digitalswitch to operate normally that 1 circuits be formed.
